561

That is a 561 automotive dome lamp. Bose and Boston Acoustics use exactly the same part.

The cold resistance is about one half of an ohm.

If you don't play it loud you could try jumping it out, but the level of the tweeter will go up a small amount.

The 561 takes a fairly long time to heat up and compress the signal. Short transients will not heat the bulb up enough to affect the sound.

You could add a relay to short out the bulb until high levels are reached.
